recommendations! Published in 2023 at "Statistics in Medicine"

DOI: 10.1002/sim.9666

Abstract: We consider the design and analysis of two‐phase studies aiming to assess the relation between a fixed (eg, genetic) marker and an event time under current status observation. We consider a common setting in which… read more here.

DOI: 10.1080/02664763.2018.1564022

Abstract: ABSTRACT This paper discusses regression analysis of clustered current status data under semiparametric additive hazards models. In particular, we consider the situation when cluster sizes can be informative about correlated failure times from the same… read more here.

recommendations! Published in 2018 at "Biometrics"

DOI: 10.1111/biom.12709

Abstract: Multivariate current-status data are frequently encountered in biomedical and public health studies. Semiparametric regression models have been extensively studied for univariate current-status data, but most existing estimation procedures are computationally intensive, involving either penalization or… read more here.

recommendations! Published in 2020 at "Biometrics"

DOI: 10.1111/biom.13317

Abstract: Panel current status data arise frequently in biomedical studies when the occurrence of a particular clinical condition is only examined at several prescheduled visit times. Existing methods for analyzing current status data have largely focused… read more here.

recommendations! Published in 2017 at "Statistica Sinica"

DOI: 10.5705/ss.202014.0153

Abstract: In many clinical studies, patients may be asked to report their medication adherence, presence of side effects, substance use, and hospitalization information during the study period. However, the exact occurrence time of these recurrent events… read more here.

recommendations! Published in 2020 at "Statistica Sinica"

DOI: 10.5705/ss.202017.0156

Abstract: This study investigates regression analysis of multivariate current status data using a class of flexible semiparametric transformation frailty models. The maximum likelihood estimation procedure is derived for the problem. In particular, a novel EM algorithm,… read more here.
